In the late 1990s and early 2000s they
had these beggar sites. People went there, made a profile, begged for money
from strangers aka cyberbegging. Most of those sites are gone. Cyberbeg.com is
still up. They became the top beggar site decades ago.
On Facebook you should be able to pin
a post with the ZELLE QRC or the PayPal link and label it The Tip Jar or
something.
The ZELLE QRC works while using the bank app. The PayPal link works like a link it'll take the person to a checkout page that was configured in the PayPal account. You can use my PayPal link as an example for how to configure the PayPal page.
DO NOT call them donations. That is
actually for charitable organizations.
